Here is just a simple program that uses the (http://gbatemp.net/threads/jnuslib-java-nus-library.452954/).
The usage should be pretty self explaining.

STILL EXPERIMENTAL. Bugs may occur, please report them!

Features

Decompressing a .wux back to .wud
Extracting titles from the GI or GM partition

 -verify <wudimage1|wudimage2>          Compares two WUD images to find differences

Examples

Getting .app files from an Wii U Image:

Extract .app etc. from a WUD:

Get .app files from "game.wud" to the folder "extracted" with game.key in the same folder

java -jar JWUDTool.jar -in "game.wud" -out "extracted" -extract all

Extract .app etc. from a WUX (compressed WUD):

Get .app files from "game.wux" to the folder "extracted" with game.key in the same folder

java -jar JWUDTool.jar -in "game.wux" -out "extracted" -extract all

Extract .app etc. from a splitted WUD (dump with wudump):

Get .app files from "game_part1.wud" to the folder "extracted" with game.key in the same folder

java -jar JWUDTool.jar -in "game_part1.wud" -out "extracted" -extract all

Compressing into .wux examples:

Compress a .wud to .wux:[/B]

Compress a "game.wud" to "game.wux"

java -jar JWUDTool.jar -in "game.wud" -compress

Compress a splitted game_part1.wud to .wux:

Compress a "game_part1.wud" from a wudump dump to "game.wux"

java -jar JWUDTool.jar -in "game_part1.wud" -compress

Decryption game files examples:

Decrypt a WUD image to game files

Input can be a .wud, game_part1.wud or a .wux. This decrypted the full game partition. Given a game.key and common.key in the same folder.

java -jar JWUDTool.jar -in "game.wud" -decrypt //WUD
java -jar JWUDTool.jar -in "game.wux" -decrypt //WUX
java -jar JWUDTool.jar -in "game_part1.wud" -decrypt //game_part1

Decrypt a single file from an WUD

Input can be a .wud, game_part1.wud or a .wux. This decrypted the full game partition. Given a game.key and common.key in the same folder.

Extracting the code/app.xml file.

java -jar JWUDTool.jar -in "game.wud" -decryptFile /code/app.xml
java -jar JWUDTool.jar -in "game.wux" -decryptFile /code/app.xml
java -jar JWUDTool.jar -in "game_part1.wud" -decryptFile /code/app.xml

Extracting all .bfstm files.

java -jar JWUDTool.jar -in "game.wud" -decryptFile /.*.bfstm
java -jar JWUDTool.jar -in "game.wux"  -decryptFile /.*.bfstm
java -jar JWUDTool.jar -in "game_part1.wud" -decryptFile /.*.bfstm

Extracting the folder /content/Sound

java -jar JWUDTool.jar -in "game.wud" -decryptFile /content/Sound/.*
java -jar JWUDTool.jar -in "game.wux"  -decryptFile /content/Sound/.*
java -jar JWUDTool.jar -in "game_part1.wud" -decryptFile /content/Sound/.*

Compiling

mvn clean package
